xtable：添加了额外的列并且使用对齐参数时出错

Question

我很难生成 LaTex 格式 table 我想使用 xtable 包。我正在尝试做三件事：

第一列不是简单的编号行。
让列的宽度固定。
使用 longtable 环境因为它是一个大 table.

这是我要导出为 LaTex 的对象 table:

structure(list(Name = structure(c(23L, 20L, 21L, 22L, 14L, 11L, 
12L, 13L, 15L, 5L, 4L, 3L, 2L, 6L, 7L, 8L, 9L, 10L, 17L, 18L,

-29L))

如果我只使用命令 xtable(df)，我会得到四列 table，其中第一列只是对行进行编号。我怎么不能这样做？

编辑：我被告知链接的解决方案中存在拼写错误。我已经在这里修复了它，但我仍然得到同样的错误。

我知道 xtable 有一个对齐参数，但是当我使用（从 this solution 复制）

xtable(df, align=c("l","l","l","p\{5cm\}"))

我得到一个错误：

\{ is an urecognized escape in character string starting ""p\{".

我试过使用双反斜杠，但也没用。

一旦我解决了前两个问题，我相信命令就是 print(df, tabular.environment = "longtable")，正确吗？

Answer 1

要修复错误，请在 align 字符串中使用两个反斜杠，如下所示：

xtable(df, align=c("l", "l", "l", "p\{5cm\}"))

您的数据框没有行名，打印 xtable 对象时默认包含行名，因此它使用行号。为避免这种情况，请在 print() 函数中使用 include.rownames=FALSE。

print(xtable(df, align=c("l", "l", "l", "p\{5cm\}")),
      include.rownames=FALSE,
      tabular.environment="longtable")
